摘要: 黄瓜、西瓜、西葫芦经授粉或外源激素处理的子房和黄瓜未经处理的子房的可溶性糖和可溶
性蛋白质(Pr) 含量, 花后4 d 比开花当天分别增加约1/ 2 和1 倍以上, 西瓜和西葫芦未处理子房则分别下降1/ 2 和3/ 4。子房POD 活性与子房发育呈明显负相关, POD 活性高时子房不膨大, 反之则子房发育迅速。

Abstract: The changes of soluble sugars , soluble proteins (Pr) and POD activities in the early developing ovaries were studied by using cucumber (Cucumis sativum L. ) , watermelon (Citrullus lanatus Mansfeld) and pumpkin (Cucurbita pepo L. ) as sample in this experiment . The result indicated : in normal fruiting ovaries , contents of soluble sugars and soluble proteins increased about 50 % , or 1. 0 times during 0 - 4 days after bloom , respectively; POD activities decreased markedly during 0 - 4 days after bloom. But in abnormal ovaries , except that POD activities were rising , soluble sugars and soluble proteins decreased markedly during 0 - 4 days after bloom.

Key words: Cucumber, Watermelon, Pumpkin, Ovary, Soluble protein, POD
